It works in a Linux browser, so you can create and download the QR code without installing a package. I’d still test the downloaded code on several phones before printing it.https://community.element14.com/members-area/f/forum/57339/esp32-software-defined-radio/238608Fri, 09 Oct 2026 13:02:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:ab375d3e-1143-4527-99a3-b66fd76fc724spindenWhat a great fine!

Those projects all work with the debug instructions left in the firmware that provide raw I/Q samples, they don't have any impact on the analog chain that is precisely tuned to those two bands. Getting to work outside those bands is likely impossible because the debug commands do not have anything even close to changing the tuning frequency like a SDR has.https://community.element14.com/members-area/b/blog/posts/stm32g031f8p6-exploring-a-compact-cortex-m0-microcontroller-for-embedded-projectsFri, 09 Oct 2026 03:38:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:38f4498e-f642-457c-a030-95d679871ea6LeorrChoosing a microcontroller for an embedded project involves balancing processing performance, memory capacity, peripheral integration, power consumption, and PCB space. The STM32G031F8P6 is an interesting option for developers building compact control systems and general-purpose embedded devices. Based on the Arm Cortex-M0+ 32-bit core, this microcontroller operates at up to 64 MHz and provides 64 KB of Flash memory and 8 KB of SRAM. Its integrated peripherals make it suitable for projects that need reliable control and communication without requiring a high-end processor. Key Technical Features The STM32G031F8P6 offers several features that can simplify embedded hardware design: Processing performance: An Arm Cortex-M0+ core running at up to 64 MHz. Memory: 64 KB of Flash and 8 KB of SRAM for firmware and runtime operations. Communication interfaces: I2C, SPI, and USART interfaces for connecting sensors, peripheral devices, and external controllers. Analog input: A 12-bit ADC for reading analog sensor signals and monitoring voltage levels. Timer resources: Multiple timers for timing control, PWM generation, and periodic tasks. Power management: Low-power operating modes that can help reduce energy consumption in suitable applications. These capabilities provide a practical foundation for embedded systems that combine sensor acquisition, data processing, and device control. Potential Applications The STM32G031F8P6 can be considered for a range of applications, depending on the system requirements and available peripherals. Sensor monitoring: Its ADC and serial interfaces can support sensor-reading systems that collect measurements and communicate with other devices. Small control systems: Timers, GPIO, and PWM functions can be used in simple automation controllers, status indicators, and actuator-control circuits. Consumer electronics: Its integrated peripherals may help simplify control boards for household devices and electronic accessories. Low-power embedded devices: Sleep and other low-power modes can be useful for battery-powered designs when firmware and peripheral operation are optimized appropriately. Development Considerations When starting a project with the STM32G031F8P6, developers should first confirm that the available Flash and SRAM meet the firmware requirements. Applications involving communication stacks, data buffers, or complex control algorithms may need careful memory planning. It is also important to review pin assignments, peripheral multiplexing, ADC input requirements, and power-supply design before finalizing the PCB. STM32CubeIDE and the STM32CubeG0 software package can provide a starting point for configuration, firmware development, and debugging. For the exact STM32G031F8P6 variant, consult the official datasheet and pinout documentation to verify package-specific details and electrical limits. Conclusion The STM32G031F8P6 offers a useful combination of 32-bit processing, integrated communication interfaces, analog conversion, and timer resources in a compact microcontroller package. For engineers developing cost-conscious embedded control and monitoring systems, it is worth evaluating against the project's performance, memory, power, and interface requirements.

It is worth seeing the video if you've not seen it before (quite long but it is possible to skip to 11 minutes into the video to listen to it in action). www.youtube.com/watch From what I can see, it is a well-implemented HF receiver, with a lot of features, and yet easy-to-build, the Pi Pico does all the DSP as well as dual quadrature oscillator. It uses a very decent mixer and has some filtering, and they've put in a lot of thought into the features.https://community.element14.com/members-area/m/managed-videos/151889Fri, 09 Oct 2026 02:42:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:1aded512-ce54-4046-98d0-01cc5a81c7d8shabazThis video highlights the operation of my implementation of the Pi-PicoRx designed by Jon Dawson.

As part of our moderation process before this, and always on user account creation, we require(d) members to have their first name and last name on their account. With a website release by the development team, the moderation process accidentally captured accounts that registered during the period of time where you weren't able to update your shipping details, or personal details, and that meant a number of accounts were marked as 'abusive/for moderation' unintentionally. If you've been caught by this, you need to 'Report a Problem' with your details so that your account can be updated and you'll be able to login to the site as normal once your account is resolved. Alternatively you should have received an e-mail where you can "appeal" the disapproval, and this is the best way to raise attention to your account needing approval. During this time though, moderation does still work 'as intended' and your account may have been correctly captured for disapproval, in these cases, your account will not be restored, and will not be restored if we see any other security reason not to restore it. In cases such as these, this may not be disclosed to you. Thanks for your patience on this matter.account creationmoderationabusive accounthttps://community.element14.com/members-area/f/forum/57320/we-need-you-to-help-shape-the-future-of-our-learning-center/238578Wed, 07 Oct 2026 06:30:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:4fa2cf9a-3319-4fcf-932b-9f40a7aa4201Gough LuiI was going to suggest Quality Learing Center as an option ... jkzjkz.
