How long does it take to call the interrupt function of comparator?
I tested with NUCLEO-F303ZE (72Mhz clock).I checked the time when comparator makes interrupt as below ------------------------------------------------------------------------------------void COMP7_IRQHandler(void){ DRV_GPIO_Port->BSRR = (uint32_t)DRV...
Start condition for I2C not working.
I am using an STM32F411, and am attempting to use I2C to communicate with an MPU-6050 (relevant datasheet info attached).I've tried to setup I2C in accordance with the timing requirements on the MPU-6050 datasheet: #define MPU6050_PIN_CL (6) #de...
How to port the NFC Reader Library to the STM32 environment?
Hi Community :)I currently using the NXP CLEV6630B RFID reader (chip is SLRC610) for our medical project, and I am using STM32H7 as a host microcontroller.Did anyone do something like that and has ported the NXP reader library to match the desired en...
Configuration of SPI for STM32F429 for writing/reading eprom AT25080/
Hi amazing community... I have a legacy project developed with STM32System workbench..I am trying to configure the spi to working with a eprom memory..I cannot use the cube generator so I have to implement the init of the HAL by myself.I made a test ...
I2C - Adding a registry & value.
Hi, I want to try sending data to a slave consisting of several registries and have seen code example:-uint8_t buf[2];buf[0] = register_addr;buf[1] = data;HAL_I2C_Mem_Write(ftHandle, slaveAddr, buf, 2, timeout);Would this work in practice? As it is m...
Bitfield registers acess
Hello I am not very familiar with the Low-level stm32F register,I have a question about the definition of each register in the TIM_TypeDefI want to have a separate access to each bit, It is possible?I the stm32F429xx.h I have this:typedef struct{ __...
Detect GPIO Low/High state without using interrupt or busy/wait strategy
Hi I want to detect a GPIO turning low/high in less than 1 mili/sec granularity.I can use an interrupt (edge) or I can busy/wait with HAL_GPIO_ReadPin which would be in 1 mili/sec granularity because of the systick.Is there any other way of doing tha...
STM32F407 What is normal ADC accuracy error?
Hello. I have an external circuitry that I want to monitor voltage. It can go up to 48V hence I have used a big voltage divider. I am using 220K and 10K resistors for my voltage divider.At the moment, I am measuring 24V external voltage. After the vo...
[STM32F769] Lost debugger com
Since the initial configuration, the communication between Cube and the STM32F769 board has been OK.As I had a problem with the SDRAM configuration, I tried to solve the GPIO conflicts listed in the IOC.After a modification (I don't know which one) (...
