Hello,On my custom designed PCB, there is a STM32F7 processor. With SPI DMA interface, I try to get the converting values of the external ADC. But everytime I get 3.1V in debug session. So how can I read the correct values based on the input signal?w...
My board has QSPI NOR memory (MT25QL256, 32MB) and STM32H750. I used Studio, CubeMX and CubeProgrammer to work with QSPI external memory on F746G-Disco board with no problem. But I have problem on my board with QSPI. My H750-MT25QL schm is same as in...
Looking for confirmation that the SDRAM data bits can be swapped within their byte lanes (D15..D8, D7..D0) to reduce the routing complexity. We are using vanilla SDRAM (non-DDR), specifically the ISSI IS42S32800G.Thanks.
Hi all - Happy NY!I've a stm32H743ZI2 (nucleo) and am using the following code to init the IWDG __HAL_RCC_WWDG1_CLK_ENABLE(); __HAL_DBGMCU_FREEZE_IWDG1(); //not working!!!? // Reload = (LsiFreq(Hz) * Timeout(ms)) / (prescaler * 1000) hiwdg.In...
Hi ST Communities,My hardware choose is IS61WV51216BLL SRAM, 512 * 16 bit, the question now is whether the written data and read data are different, there will be a part of the data loss when reading, now is not sure there is something wrong with the...
Hi I have been looking for the sample code to implement the DFSDM using MEMS mic using a Single Data and Clock line. I am using CudeIDE 1.0.2V. The MCU I have H743ZI and the mic IM69D130 using a common Data and Clock lines. Channel 4 using Filter0 an...
does it need some time delay between two read multiple bytes function?is there some tip about it
Given figure can be found in the respective erratum in ES0250 Rev 7 ('L476 errata).And please remove the "modern feel and look" from this and all other errata.JW
Helloi am using UART string command in switch to start stop adc DMA. Start, Stop command work fine only once but after stop command when i give start command ADC DMA does not start again.Belo both function ADC init(CUBEMX created) and ADC_StartStop(O...
Hi Everyone. I have a question relating to my project, and I think I have it tracked down to one problem area. As a hobbyist, I don’t get the time to work on my projects as someone working in the Industry does, and figuring it all out take so much lo...
