Hi there,We use a STM32F777VIT6 in our application.We tried to use the internal ADC to monitor the voltage of the backup battery.In principle, this works, but we noticed two effects that we cannot explain.The data sheet for the STM32F7 states that VB...
Greetings to all,I'm new with this development board. I download the I-CUBE- LRWAN for end node creation on NUCLEO-L073RZ + SX1272 mbed shield. I tried to send data over UART to my NUCLEO Board, then send it to my Lora gateway but I am not able to re...
I am having a strange (to me) issues trying to program an STM32H743VI.I have had the PCB manufactured and assembled by a different supplier and all of a sudden I cannot program the STM32H743....I do not have the NRST pin back to the STLink-V2, only t...
I have a custom designed board using a STM32F429IET6 and LAN8742A.While attempting to bring-up ethernet and LWIP (fails w/o LWIP at the same spot) the code continuously fails in stm32f4xx_hal_eth.c in `HAL_ETH_Init` while waiting for the SW reset to ...
We are generating PWM using the STM32F429 TIM10 -- In this call-back function we counting the PWM pulses and , when counting pulse is equal to the total pulse then stop the PWM.But in this code counter are counting the properly counting the pulses bu...
I am using st-flash version of 1.8.0 to flash the binary into Nucleo H563ZI. In this process i have used erase command "st-flash --connect-under-reset erase" to check whether the hardware works or not. For the erase command i got below error"st-flash...
Hello I need to send a string via USART every 500ms. I tried to use DMA that seems to be easy to configure. USART transfer works but only without DMA (test in while main cycle). I do not see any problem in DMA configuration. Can you tell me it there ...
Hi , I tested example " I3C_Controller_Private_Command_IT " with Controller H503RB board and modified for JEDEC SMBUS for DDR5 ( JEDEC smbus is more simple than MIPI I3C ,No DynAddrAssign function , Initially I2C after CCC SetAASA , it ...
Greetings Everybody, I have Nucleo - F207ZG board. I have attached external 3.0 V coin battery to VBat and GND. I am configuring board for RTC peripheral. After configuring RTC time and again rechecking after 1 day the time starts to move ahead or ti...
I am using two quadrature encoders through the STM32F411CEU6 timer encoder mode. Here is the graph for one of their CNT values:As you can see, it takes about 400ms to update the value, but when it does, it seems accurate. How can I make it so that it...
