I'm trying to replace the oscillator of the STM32F407 since I can't find anywhere the one listed in the bill of materials:It's a 8Mhz crystal oscillator from jfvny and it is in a HC-49/S package, the load capacitance is 20pF and frequency tolerance o...
Hi,l'm using the STM32F072RB for a programmable periodic wakeup of a system. I have some troubles in the RTC calibration. I have a 8MHz crystal oscillator connected to HSE and, since I won't put in stop/standby mode the mcu, I would like to use it as...
Hello everyone.I want to port SPI emulator library in master mode which is originally write for STM32F401RE-Nucleo to stm32f429. In application note AN4678 it says in order to make clock for we use TIM1 channel1 and channel2. In discovering the code...
Hi everyone, I am new stm32 platform. Is there anyone can point me about using the STM32F7 internal SRAM code. Most if the example code is using the external SRAM. In my case, I am using the internal SRAM so I change the starting address to 0x2001 0...
I’m very much still learning the STM32 and all my work so far starts with examples. I can get the ST provided RTC example STM32F413ZH-Nucleo -> Examples -> RTC -> RTC_Calendar running and it seems to work fine. But when I put the code from that examp...
Hi, I am using STM32H743Zit6 Dev. Board. while hex file file generation , program code is in 0x08000000 and upload it works fine.when i want to generate bin file, so i use the following steps. Bin file generate is successful but program code is...
(After installing the virtual com port, cannot access)(Current visual with the recognized STM32 link Ukeil and other tools recognize)I used to see com ports via the device manager in windows 10. I've installed the Link 009 drivers for stm32 boards an...
Hi Guys,I have an F7 and want to read in a data stream. Transfer is synchronous, constantly on and data rate is about 2kBaud. 1 Frame consist of 64 bits, in which i have to find a pattern for the start. I want to use a DMA with maybe 128 bit transfer...
The SPI does not work correctly in the slave mode when CPOL=0 and CPHA=0 or CPOL=1 and CPHA=1.When transmitting some bytes, the slave SPI distorts the data and terminates the processing of the frame prematurely (during the seventh pulse of the clock ...
We have to write firmware for a STM32H745. It was not our decision to use a dual-core version and we are pretty sure that a single M7 core will easily do the trick, so the next iteration of the PCB will contain a single core variant. Now we would lik...
