I2C slave address masks interferes with slave addresses 0-7
Unfortunately, I cannot post any code for this question but I believe it relates more to the HAL library and the i2c address matching hardware of the STM32 microcontrollers.I am working on emulating multiple I2C slaves in the address range of 1-24 on...
Resolved! CAN transceiver on stm32f407 discovery
Hello dear friends,It's been a week since I worked on the CAN transceiver and couldn't make it work. I have set up the chip rcc, bit rate, and receive interrupt of CAN, set the receive filter, and the receiver id in transmission, with no success. I h...
STM32F030F4Px USART problem
i'm using STM32F030F4Px for MODBUS Master Slave communication based on USART (RS485 communication). i'm using 9600 baud rate, 8bit 1 stop bit communication with DMA and HAL. Master is transmitting 8 bytes to slave after 10 or 20 msec which are receiv...
Why is my the output voltage from the internally connected PGA op amp to ADC outputting noise?
For reference I have a nucelo G491RE board. Aim : I am trying to connect 4 sensors which have a low output signal to be amplified and then sampled by 2 ADCs (2 sensors are connected to one ADC). The problem is, is that I need a really high sampling r...
Why am I getting a "Debugger Update Job" error when running the debugger?
I run the debugger with error on the first attempt. On subsequent attempts the debugger pops up a "problem Occurred" dialog box that says;Debugger Update Job has encountered a problem.An internal error occurred during; "Debugger Update Job"Opening t...
Resolved! STM32L4 : Using a part of QSPI external Flash Memory as a frequently updated data log, accessible by a PC with USB MSC (Faisability demand)
Hello everyone,I'm working on a STM32L4 project which embeds a QSPI external Flash Memory (not yet sourced but doesn't matter).This QSPI Flash Memory would be splitted into 2 parts, one for TouchGFX Images and one for 10MB Filesystem. This FS will ha...
I have chosen the STM32F469IGT6 for a product which we are about to develop. However, I am unable to locate this product with any of the ST Distributors with lead times of almost a year even though ST marks this part as ACTIVE in its website.
Shall I go ahead with this part or can someone suggest an alternative which is available off-the-shelf or with reasonable lead times
