FIFO Undderrun issue in STM32H757 Eval board
Hi Guys,Quick question. We are using STM32H757Eval board for an application. We are not using in-built DSI display, instead, we use RGB display of size 1024*768. We are using 32bpp and transmitting RGB via LTDC. As per the datasheet, the maximum perm...
How to trigger CAN Callback (STM32L452) ?
I'm currently trying to get a message from another can device and I can't figure out why my callback isn't triggering.I can transmit a message without any problem however I can't receive any. I am using vector CANalyzer to check my bus.I was trying t...
Resolved! Writing assembly code in a C program to turn On/Off GPIO pin
Hello everyone, I am trying to measure how much time is used to finish executing a function. I cannot use the timers because it adds some delay to the system. My other option is to use GPIO pins.To do this, ISET a pin at the start of the functionRESE...
I2C driver always busy after first use
I'm using the HAL_I2C_Master_Transmit_DMA driver on an STM32L412. I am transmitting 8 bytes of data to an external 4 channel I2C DAC - I have only one device on the bus. The first use of the driver works fine as confirmed by using an oscilloscope on ...
Stop mode 2 with external SPI peripheral
Hello ST community,I have QSPI flash and an environment sensor based on SPI with stm32l496rg development board.If I put controller in stop mode 2 without sensor and flash current consumption of system is 3uA.If I connect flash and sensor then in stop...
We are designing circuit for IOT NODE using ST 32L4. We would like know whether we get technical support from Application Engineers for Validating our design
Please inform the procedure to get technical support from you
Is there any difference between usart6 and usart 1? Usart6 gives me problems with same configuration as usart1, which is working fine.
Hello community,I have a problem with using usart6, although usart1 is working fine.My setup: STM32F439, usarts connected to a dual ftdi chip, so I have two com ports on the pc to choose of, which represent usart 1 on usart 6 resp.Also direct usb con...
About the I2C of STM32F030C8; from the datasheet, PIN 42/43, 45/46, They all could be I2C1; pin 21/22 or 35/36, which is I2C2?
please review the datasheet,--4 Pinouts and pin descriptions-- from the datasheet, both PIN 42/43 and 45/46 could be I2C1; both PIN 21/22 and 35/36 could be I2C2; which is right exactly?
