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...
I was not involved in ST MCUs (STM32F769 specifically) until now. I understood that CPU gets stack pointer at start, from address 0, but what there exists is RAM - which is undefined after power up. Then, how can I force some "reasonable" SP value in...
Hi, Im searching way to avarage two unsigned 32 integers.Is there any hardware help in doing this with stm?
