How-to feedback for possible correction in datasheet?
On page 22 of this datasheet:https://www.st.com/resource/en/datasheet/stm32h753xi.pdf"Figure 1. STM32H753xI block diagram" shows 200MHz and 400MHz.Shouldn't this be 240MHz and 480MHz instead?The document states "Updated Figure 1: STM32H753xI block di...
Resolved! STM32L451 with UART at 1200 7N2 with different clock tree configurations
Hello,I have an app working fine with a device that works at 1200bps 7N2 using a Clock Tree with HSE CLK configuration at 8MHz.If I change the Clock Tree to work with PLL to other frecuencys like 16,32,64,72 every work fine, even if I config at rare ...
Resolved! STM32F103VG Flash Memory Write failure
Hi, I am using STM32F103VG micro-controller. I am trying to program the memory in range 0x8014000 to 0x8090000. My code is able to program the memory till 0x807FFFF but after that it failed to write into memory i.e. problem happens after I start writ...
Hey guys, im new to st and im having hard time with receiving data VIA uart. im trying to receive data with unknown length, decided that the best thing for my application would be idle line interrupt.
my problem is that the DMA only writes to the first address of the buffer, means that when i look on the buffer, the last byte of the message is stored in the first place of the array, and the rest of the data is overwritten.what could be the problem...
STM32F103 eternal interrupt not work without for loop delay.
eternal interrupt routine works with some delay if i remove delay then it not work what is the reason how can i solve this?*code work with some for loop delay.void EXTI3_IRQHandler(void) { /* USER CODE BEGIN EXTI3_IRQn 0 */ for (int z = 0; z < 50...
STM32F103R8T6 no CAN interrupt?
CubeMX ver 5.4 F1 package ver 1.8.0 and CubeMX ver 5.5 F1 package ver 1.8.0 when using CAN pins PA11 and PA12 the receive interrupt does not work. If you make pins PB8 and PB9 everything works. It also works on any pins if you configure loopback mode...
Hi all, I have a project that need to use NFC PN532 read / write Mifare Classic card with STM32F429Zi MCU communication via HSU. I'm in the initial stages of project, don't know what i should do, and what is the best path.Please help me.Thank you so much

config OPAMP in non-inverting configuration with the output of opamp connected to ADC: is it possible?
Good morning,i' m working with stm32g4 and formy application i need use internal opamp in non- inverting configuration withexternal resistor how show the figure below (figure form AN5306). I don’t understand if is possible connect the output of opamp...
Hi Everyone, How to average ADC values in STM32F103VBTx using DMA method?
I am using STM32F103VBTx. I have configured ADC using DMA method. We are getting some noise on PCB due to which ADC values are not captured properly. We see a lot of variations even after Calibrating ADC values through software. We are trying to eli...
