Hi ST.I'm using STM32 L4P5 as a Master in I2C.slave device is slow to write data, so I did the slave device do clock stretching for a moment.Is there any enable related to clock stretching on L4P5?If so, what's the way to enable it?thank you
Documentation is a bit vague with respect to use of PC13/14/15 as GPIO while MCU is in SHUTDOWN mode. My understanding is that these pins can be used in the backup domain (my VBAT is connected directly to VDD).I understand that I could SINK up to 3mA...
Hello,I have a general question about DMA which I am currently using to transfer a LUT in the memory to control PWM output.The LUT changes periodically and at the moment the DMA is triggered with a timer. What I would like to know if it is safe to ch...
Hello.I'm testing ADC with DMA on STM32G071. I wanted to have interrupt on transfer complete, but I had trouble clearing TCIF flag in ICFR register. Even if I cleared the bit, ISR was entered again immediately. I don't have circular mode set neither ...
I'm trying to connect a ILI9341 based parallel LCD to STM32F412RE. I have successfully connected that to the STM32F412ZG in the past, but that was using the pins in the H/G ports not available in the 64 pin package. When configured for pins on the 64...
Figure 29 of the STM32G473 datasheet calls out an unspecified, internal RADC. Is there any data on this internal resistance?
Hi, i am trying to implement CAN Protocol in STM32F103C8 Controller in Normal Mode 1) not knew what should be the hardware required for implement Can protocol2) is their any bug in stm32cubemx code generate using library 1.8.0
Hi, I have been trying the Flash dual boot example from version1.3.0. I am following the steps as given in the readme.txt, flashed the bank2 FW from location 0x08040000 and used the debugger to flash the bank1FW. I triggered a bank swap by pressing t...
