I need someone who is well versed with STM32F4 series. I have to program a custom made PCB with an on board STM32F407VGT6 (100 pin package), the details of which will be discussed in personal chat with bidders. A similar type of PCB was programmed before this by my superior so some of the modules are already ready, and 2 others need to be programmed. For example: The ADC needs to work in simultaneous mode, which is already programmed (might need some editing) and a DAC and one more module with SPI interface needs to be coded completely from scratch. ****************** Information for bidders************************************* ****************** Please only bid if you agree to all of the points below******* Time constraint: The PCB is getting ready (will be printed, soldered and ready by 20th July. You can begin with the code today, tomorrow, whenever you want, but the testing will only be possible after 20th. And all the coding, testing, troubleshooting has to be completed by the end of July. The sooner the better. Money: You can bid based on the budget but I have some experiences with freelancers who refused to start working without an advance and after paying around 200 euros, were not able to finish the tasks. So please don't expect an advance payment. Your code is of no use to me if you leave it unfinished. Ofcourse, if we determine if there is some problem with the hardware or PCB, then you are not responsible. And of course I will make milestones for your security. Software: You can use whatever you want, but I will be using IAR + cubemx. Access: I am willing to give you remote access to my laptop for 3-4+ hours a day so that I can easily understand what you are doing. (Its completely optional). You can also do this in the testing phase. It will make things easier for both of us. Code quality: I don't care if the code is newbie level or efficient, as long as it works. Bonus 1: You get a 100 euro bonus on top of your bid if you finish the work and I have a fully functional device by the end of July. Bonus 2: You get a chance to change your bid after I show you the circuit and give you all the details as I can't upload it here and I'm aware of the fact that its difficult to get an idea about the amount of work and time that needs to be put in without knowing the details. Preference: I usually prefer new freelancers as they charge less but this time I'm not concerned about the money, I NEED THIS WORK DONE IN ANY CASE. Advantages: Consider this a test product, if I like your way of working and I find you reliable and professional, I will give you more projects in future. I have at least 1 new thing to outsource every month. REMEMBER THAT YOU ARE ONLY CODING DAC AND SPI. EVERYTHING ELSE IS JUST AN ASSEMBLY JOB WHERE THE CODE IS READY AND YOU HAVE TO DO MINOR CHANGES (FOR EXAMPLE PIN NUMBERS, ETC). DON'T OVERBID.

I use STM32CubeMX and Atollic Truestudio for my development with STM32 devices - as I can not run IAR on a Linux operating system. I do not think that would be a show-stopper but just wanted to let you know in advance. Do you have a preference for use the HAL or LL drivers for peripherals? I use the HAL drivers for the ADC and SPI peripherals. What module are you connecting via SPI? Also ... Are you using FreeRTOS - or some other RTOS? I have a STM32F4 development board which I could use for initial testing. Will you be able to ship a PCB to Ireland at some stage? I may indeed need to revise my bid after you provide more information. In the meantime, please note that this bid is PROVISIONAL. I am based in Ireland.

Hi, I'm an embedded software engineer with extensive STM32 experience. I understand you need some changes to your existing ADC code and also some new interfacing involving DAC and SPI peripherals. I can execute this efficiently and I always work fast, as my reviews show. Send me the relevant schematic, so we can discuss details.

I am an experience about embedded programming with IAR on STM32 MCU. Not only me but I have a team working on it about SPI, UART, I2C, I2S, ADC/DAC.. So, please share circuit diagram, current source code and what is the issue -> I can finish it in the righ way and surely you will be sastified. Regarding SPI module's driver, just share me about the device's progamming manual document for study so we can start programming on it. Not only this project but we need to co-work for long time. Thanks & best regards, Can,

I've worked with the STM32 series of microcontrollers for 5+ years from L0 to F7, including F4. I'm quite knowledgeable with all STM32 peripherals and have done ADC to DAC comms through DMA with some DSP in the middle. My STM32 workflow is STM32CUBEMX with coding done in Atollic TrueSTUDIO though I'm happy to move to the new CubeMX IDE if required. I work with STM32 in my standard day to day job so this shouldn't be an issue.
