Bonjour Mohamed, comme promit , pourriez vous developper un software /STM32 / pour faire des mesures resistances 1% sur la gamme 0 ohm -> 1Mohms
Bonjour Omar A., Je m'appelle Ludovic Montanier, je suis aussi indépendant. Mais plutôt orienté électronique. Je travaille sur un petit module emetteur/recepteur 868Mhz low power avec comme composants principal un STM32L04 + CC1120 Aujourd’hui je dispose de 2 protos, ils sont fonctionnels, j’ai débuté la programmation sous STM32 cube IDE. Je programme bien le chip STM32, la liaison SPI entre le STM32 et le CC1120 fonctionne bien, j’écris bien et relis bien les registre. L’un est programmé en émetteur et l’autre en récepteur Mais la communication entre les modules ne se fait pas... Est-ce dans vos cordes pour m’aider à débugger et finaliser m...

I'm in need of a skilled C programmer with extensive experience in firmware development for STM32 and LPC1768 microcontrollers. The primary focus of this project is creating efficient and effective firmware to enhance the performance and capabilities of these systems. Ideal Skills: - Proficient in C programming language - Extensive experience in firmware development - Deep understanding of STM32 and LPC1768 microcontrollers - Ability to write clean, efficient, and well-documented code Experience: - Proven track record of similar projects - Demonstrated ability to meet deadlines and work within budget constraints - Excellent problem-solving skills - Strong communication skills for regular project updates
...selected FPGA is iCE40HX1K (or iCE40HX8K) so you must have access to their development platform (iCEcube2) [you can request free access through them]. The goal is to use a standard high-speed 8-bit ADC/DAC for encoding/decoding, but we could also potentially use ADV7280/ADV7391 instead. We currently have a setup that retransmit the video signal through the FPGA with the regular ADC/DAC, but it has a lot of static in the output video. Solving this issue would be the first step or deciding if we need to switch to ADV7280/ADV7391 right away. It would really help if you have some components (FPGA, ADC/DAC, VGA Camera/Monitor) on your side, but otherwise we can run some tests on our setup. We need somebody with previous experience with analog VGA NTSC/PAL signals an...

This is to bring attention to my programming CONTEST at: https://www.freelancer.com/contest/CrossPlatform-basic-example-app-with-JNI-Flutter-or-KotlinNative-Multiplatform-for-AndroidiOSetc-EST-2514642/details So do not BID here, instead GO TO the CONTEST at: https://www.freelancer.com/contest/CrossPlatform-basic-example-app-with-JNI-Flutter-or-KotlinNative-Multiplatform-for-AndroidiOSetc-EST-2514642/details
The basic example app is simple, just include several small binaries of Hello-World compiled/built with Rust/C/C++/golang and the app must execute them and display the app message in an activity or 'view'. So you will need to use JNI or ffi or channels or bridges if using flutter etc. You can use whatever cross-platform method you prefer. You must provide all sources and binary for Android and one other platform. Clear? The app will simply call several versions of "Hello World!" binaries (one in C, C++, Rust..) inside the "Apk" for example, and display the Hello World output in some GUI (graphical view/user interface) of the app. You can post just the BINARIES and provide the Source Code "after" you are AWARDED the contest.
