STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
We are using the STM32L476VG Discovery Board and are trying to use the SPI 1 interface. I generated the code through CubeMX with pins PA5, PE13, PE14, PE15. After the code was generated I tried placing this example code into the while loop: HAL_G...
In my debugger settings I got there is some SWO frequency difference means before 2 or 3 days its frequency value is 10Mhz but now it is only 2Mhz and from last days I have getting some errors. So plz tell me that such errors are coming due to this ...
Hi everyone,I recently found myself having spent a lot of time working to get I2C to work on the STM32F103RBT6 (the problem: I2C begins life in the BUSY state).This is apparently due to an ADC noise problem, as described in this errata (p. 26):https:...
Hello, STM32F407vg. I am looking for some help in using a flash file system (faftfs) on SPI based NAND Flash. Are there any examples or demonstrations that I can look for to start with?
Hi,my first example for RS232 communication and my first problem.I have this output in the terminal:5 ''! Ëå˙˙˙ <00> 5 ''! Ëå˙˙˙ <00> 5 ''! Ëå˙˙˙ <00> 5 ''! Ëå˙˙˙ <00> 5 ''! Ëå˙ <00> 5 ''! Ë <00> 5 ''! Ëå˙˙˙ <00> 5 ''! Ëåë <00> 5 ''! Ëåë <00> 5 ''! ë...
Hello, I am using the Stm32F769BI MCU.I am receiving 3 ADC channels through DMA.My problem is that debugging stops in the middle due to HAL_ADC_IRQHandler during debugging.To debug again, I must press the Run button again.I want to know why inter...
Hi all,I purchased a STM324x9I-EVAL board and I'm working on with Keil uVision5I'm using the EVAL demo firmware, downloaded from the STM32CubeF4 library packageI'd like to create a file system on external flash (in my case M29W128GL) but I see that t...
Hello ,With SPI (SPI2 in my case) I experience a delay between a wite to TXDR and the start of the SCK activity in case of an empty TX fifo. It seems to be something like 5 SCK periods, so it changes with SCK frequency but this ratio remains. I check...
I configured the SPI2 port for bidirectional (BIDIMODE = 1) and rx (BIDIOE = 0), then enabled the port (SPE = 1). According to the RM the enable should immediately start sending clock pulses out the SCK pin and read data on the MOSI pin, since it is...
I have a LSE with a freq of 32.768KHz. The cube generated code uses values for AsynchPrediv = 127;SynchPrediv = 255;These values give around ~4ms resolution. Is it possible to get to ~1ms resolution?Thanks
