HiI've been struggling trying to get an Image from a Image sensor over DCMI via the GPDMA on an STM32U575.The image sensor has a resolution of 752*480, though I only want to capture 420*420, which I've configured on the sensor to output. I've also co...

AT+CICCID is the AT command you send the SIMCOMM module to return the eSIM ICCID

I beleive you register ST4SIM devices on the truphone portal.If you want to register the SIM on another network, this isn't as well defined. Though, I think it's just a matter of providing your ICCID (obtainable from the SIM7600 via the at command "A...

Hi I'm having very similar issues with my sim7600G and ST4SIM-200M. Was there any other connections you had to add, like the 20K pullup between SIM_VCC and SIM_IO? It recommends this pullup on the ST4SIM-200M datasheet, though I do not know if it's s...

I think my problem is related to alignment, when I pass the data from the DMA into a 32 bit buffer rather than an 8 bit one, the data goes through just fine. I made the assumption that passing in the memory location by pointer meant that it didn't ma...

My system clock is at maximum (160MHz), using an external crystal as the PLL souce, I've also slowed down the output of my image sensor to minimum in case it were the cause.Other than SPI1 for the sensor config, TIM1 for a usec tic and USART1 for ser...
