We are trying to interface OV2640 camera with STM32f769 in our custom board, In OV2640 datasheet the slave address is given as 60 for write operation .For writing initial configuration , below API is used" CAMERA_IO_WRITE(OV2640_I2C_ADR , 0xff, 0x01)...
Hello,Does anyone knows if ever any stm32 library been ported to CMSIS compatible ?I've seen the following post, but can't download file, and not sure about any other attempt to port HAL to CMSIS. https://community.st.com/s/question/0D50X00009XkcAISA...
Hello,I wanted to ask if STM32 (actually stm32h7) has any compliance with CMSIS-driver APIs ? (for example, uart cmsis is described here:https://www.keil.com/pack/doc/CMSIS/Driver/html/group__usart__interface__gr.html)I assume the answer is not (afte...
Hi I am using 2 nucleo f103rb boardOne is normal mode while the other one is silent mode, it works .but if 2 are both normal modes , none of them can receive messages.May I ask any possible reason for this? Thanks
Hi Everyone,I am trying to make STM32L071 as I2C slave mode.If someone have any sample code or documents please share.
Hello all,Good day!I am working on a project to drive WS2812B RGB leds using STM32F030R8.These leds needs precisely timed signals of 800KHz. I am using a timer in PWM generation mode with DMA.These leds require each bit of data to be 1.25us long.When...
Stm workbench shows jtag failure -4 when trying to set two gpio pins to high. One connected to boost conveter(enable) and other to telit modem on off.Is there any other settings I have to do to fix this error.Chip: stm32l471reGpio: port b, pin 0 and ...
Q1: [RM0008] 31.6.1 MCU device ID code, DBGMCU_IDCODE says,"0x1003 = Revision 1, 2, 3, X or Y". It looks idiot. Does it means you still don't know what your revision is even you have read the DBGMCU_IDCODEQ2: I have a stm32f10zet6 which is revision...
Hello,I am trying to switch system clock on H743ZI to PPL1. Using following code, it hangs up on checking SWS flag - clock switch begins, but never ends.I have tried setting domain prescalers before or after clock switch. The same for flash latency.I...
I have an STM32F051K8 that I burned out on a Lumenier tx5gs vtx. It still transmits video but I cannot change channels. I thought it would be fun to try and replace it. Fortunately the 3.3v, GND, SWDIO, and SDCLK pins are all broken out on the board....
