Development of AD7768-1 ADC interface library with STM32F103 MCU is needed. We have a custom PCB that has an STM32F103 MCU which interfaces with the AD7768-1 ADC through SPI. A small library was developed previously to validate the interface, the internal ADC registers can be read and written to easily. Also, an LED was attached to GPIO0 of the ADC for test purposes. The previous developer verified the interface integrity through controlling the LED through the ADC GPIO0. What’s required now is: 1- Development of code to read the measurements from AD7768. 2- Development of code to use AD7768’s internal filter function to operate its low pass filter with a cut off frequency of 500 Hz. 3- Development of code to send these measurement values to MAX3491 to be transmitted out in RS485 form. The assembled board will be shipped to the freelancer. Only an experienced freelancer should bid. Read the attached datasheet of the ADC first and if you think you can do it, then state your offer.

Hello. I am electronics design engineer and have experience with STM devices. Recently, I did a interfacing code for ADS1120 (Texas Instrument) using STM32F103 BluePill module. I am fairly certain that coding required for AD7768 will be quite similar. I have quoted my price in the bid. You will have to create milestone which will only be cleared after you are satisfied with my work. I will not ask for any partial payment. You can also check my upwork profile if you like to.. [login to view URL]~01169354ebd073848b/ You dont have to send the PCB to me, if you can give me remote access I can first try to do it remotely. Looking forward to discuss. Thanks

Hi, I have used STM32 since 2012 and familiar with most of it's peripherals including SPI,ADC,DAC,UART,DMA, etc. This project is kind of my daily activity. I have used STM32 in various project, from hobbyst to Military purposes. I also familiar with RS485 since I have use it in many occasion. I will use SYstem Workbench(SW4) Eclipse as IDE, Gcc-arm-none-eabi as compiller, and STM32CubeMx as project generator. That's my standard STM32 Development tools. But I can use arduino environment as well. Just tell me what kind of environment you prefer. For Firmware downloader usually I use ST-Link. Personally, I have became firmware engineer since 2012. If you look at my portofolio, My Team Built that robot using STM32F4 in 2012. And most of my professional project was built using STM32 Environment. I have read your description carefully, I'm clearly got what I have to do for this project. You can shiped your board here to my address. I have many clients that already shipped their product to me and most of them were satisfied with my service. Let's discuss the details of this project over chat. Let me help you solve it. Best Regards, Rijal

Hello. Im designing different electronics devices, mostly based on avr, arm MCUs and boards with them like arduino, stm-discovery etc. (autopromotion^)) You marked "arduino" - is your library made using arduino ide? Do you need a library to work in it? Or some other ide? Functionallity needed? Just setup and read? Continuous read? What frequency? Give more info and lets talk. Bid is not final due to lack of detailes for now.

Interesting job. I have worked quite a lot on delta sigma 24 bit ADCs for precise measurements. Especially ADCs from TI and Microchips (Metering ICs) and can easily assist for this driver development. I do have precision measurement tool (Keithley DMM6500) as well to validate the analog accuracy of the board. Will be an interesting job to work on. I do have extensive working experience in STM32F series (upto 4F) and I will use GCC for all the compilations. Quality assured and I develop codes mostly for STM32F for my living. Do let me know. Please note that completion time has been mentioned arbitrarily as the main testing and part of the coding can be done only after receiving the test prototype. Thanks and Kind Regards... Roy

Hello, I work on similar projects on a daily basis and can handle this task easily. I've been already working with 8-channels version of this ADC in the past. It won't be possible to set cut-off frequency at exactly 500 Hz but we can achieve for instance 430 Hz with FIR filter, 1 kSps ODR and 1.76 uV RMS noise. Exact ADC configuration can be discussed at the later stage. Do you have any constraints on the RS485 baud rate, please? Will there be more than two devices connected to the 485 bus? Based on this we will be able to calculate the required baud rate and find the best option for the low pass filter and the output data rate. Looking forward to working with you. Kind regards, Krzysztof

Dear Sir, I am an expert with more than 15 years of experience in the field of embedded systems, electronics, prototyping and PCB Layout. This is my new account and therefore you may not find reviews but I have another profile on this site with more than 50 reviews. I have worked alot with MSP430s and STM32 MCUs using IAR, Keil and other development tools. I have checked your project in detail and very happy to offer my proposal. I am resourceful and have STM32F103 Discovery board and other hardware for developing a tested code. If you select me you need not to send me the hardware and I would develop and test the code locally on the hardware at myself and you just need to load the code and test. Regards Ch
