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...
I stuck with ADC implementation understanding. Please help me to get this.In STM32L5xx reference manual (RM0438), ADC main features are given as follows (Page no. 685 in RM0438 Rev7)" Up to 2 ADCs which can operate in dual mode:ADC1 is connected to 1...
I want to know how to calculate the Timing register content on my own for the I2C clock speed, I know that it can be generated by the STMCubeMX.
Hello community,Processor : STM32F105 (Cortex M3)Compiler : GCC 6.3.1I would like to execute the following assembly instruction :udiv R3,R2,R3where :R2 = 64 000 000R3 = 1Instead of getting R3 = 64 000 000, I get R3 = 2047I tried to execute strictly t...
Dear Sir,I have a custom board board with a FW in hand.I am using IAR IDE.What I need to add the output file in configuration and load, run program.Recently I dont have IAR license yet.Could you tell me what to do?
Hi - I'm having trouble getting DFSDM input to work with DMA - I'm unable to set the `DMAEN` bit in the DFSDM register.One troubleshooting angle: What register pointer to you pass to the DMA's CPAR? I assume `DFSDM_ FLTxRDATAR` for regular (non-injec...
MCU: STM32F105RCTxFirmware Version: STM32Cube FW_F1 V1.8.0I have DMA setup to read 8 channels of the ADC into a fixed buffer and I'm having an issue where after an extended period of time (usually hours) the ADC channels are read into the wrong buffe...
I am trying to get the USART3 to work with DMA, and so far have been unable to. After the initial cubeIDE project setup, I verified that standard (non DMA) RX and TX were working fine.Moving to DMA, I was getting Direct Mode Error interrupts, and a l...
Hi,I am using STM32F746G_DISCO board to create different pages for the LCD. I see only one page with 4 tabs project already takes 300KByte flash memory code space. The STM32F746 only has 1MByte flash. So I like to store the LCD graph code related mo...
Hello everybody!I can't use USART2 in STM32G030K8 to transfer data.The TC flag of the ISR register is not set after writing data to the TDR register for an infinite time, if I use it to control the transfer of a byte, the program hangs without transf...
We have connected 7 channels in ADC2 to a STM32F769II processor. The DMA to ADC is enabled and the rank for conversion too is configured. But on testing, the ADC values are being shown in buffer location very different from its rank.This happened in ...
