In Progress

Work on existing STM code and do some additions

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.
