Hello,I am working on a STM32L073V8T6. I want to use the 1/3 bias functionnality to manage a screen.I have configured the contrast control to 3.26V, the Mode to 1/4 Duty Cycle and the Bias Selector to 1/3 Bias. But if I write something to COM0 and...
Hi i am working with stm32l051c8t6 , i am using wakeup pin 1 to wakeup from standby mode, weather is that possible to make the wakeup pin should act as wakeup pin and also as external interrupt, it should wakeup when an external interrupt is detected...
Hi,I have custom developed board that uses STM32F401RCT6TR as MCU. I have LSM6DSLTR IMU sensor on the board and MCU is communicating with IMU using I2C1 channel (PB6 and PB7). I also have 2.4" screen (ILI9341) that displays IMU values and external EE...
STM32F769I Disc：Is the function of stm32f769i dico's QSPI DDR normal?When I used the ddr mode, I could send data using 1line, but when I used 4line, the device was busy until the timeout error occurred, and the data could not be sent normally.However...
This topic is inspired by discussions in ST forum and ARM forum, where a proper cache maintenance was sorted out and an example of a real-life speculative read was detected. Also there is another discussion, where a real-life example of cache evictio...
Dear Sir, Good morning!I use STM32F407vgt6. I need chip ethernet controller with MII interface from STM. I previously used DP83848 from Texas Instr. Please recommend me ethernet controller from STMTIASincerely,Vladimir Naumenkov
When i debug SPI1 on STM32F407, program will jump to 0x00 when write DR register, MCU reset and loop continuely. when i measure the SCLK signal using oscillator, SCLK is always high after SPI1 is enabled When i write to DR of SPI1, the code jump to ...
Hi,I am using SPI on STM32H74II MCUFirst I am using a software NSS and not a Hardware NSS because it doesn't work.I need to transmit 1 byte and receive 1 byte, the two commands one after another see the simple code below : RFID_SS_ENABLE; statu...
Dear All,My customer using STM32F205ZG and I have the following issue.I am accessing dual port memory using FSMC function, but when I measured the waveform, I found that CE(CS) did not increase due to BUSY(WAIT). See picture below.setting value : "Ad...
