Hi,I am a team of two, trying to understand this custom SPI communication:The Communication is basically a variant of SPI with CPOL=1, CPHA=1. There is no framing or CS signal, which complicates parsing, and there is an additional variable length ACK...
I’m after some recommendations for a communication protocol between two stm32’s. One will be on a BMS board controlling a battery monitor IC and reading a fuel gauge and another will be on a seperate board with a charger and a power supply. The commu...
What does the 'High' optimization actually do in IAR Embedded Workbench 9.60.3 when the 'Size' option is selected, but no additional optimization checkboxes are enabled. Even without selecting any extra options(like CSE, loop unrolling, etc. ), the ...
I'm using E Design Suite to build a buck (step-down) converter circuit and would like to know if there's anything in the design that I should be concerned about. I've reviewed the schematics in the datasheets, and they seem to be about the same.I pl...
I found that the TDA7786 provides a datasheet, but based on others' code, it seems to lack a lot of content. Are there any similar technical reference documents or application manuals? I feel like I can't write the driver based solely on the datashee...
Parts#:M24128-BFDW6TP How do you know the wafer origin of the part based on the trace code? Thanks! [Moderation edit: pictures removed to avoid misuse]
Dear All,I have dev a custom pcb based on stm32h743ii series with the following Spec:Flash : 25Q256JVENSDRAM: W9825G6KH-6lcd wiki 7 inches resolution 1024 x 600What i have configure ltdc on sdram at adress 0xC0000000 is ok .Now is the configuratio...
Hello ST community has any one an idea what this ST chip is as shown in the picture?I haven't found any datasheet of this device.
Hello, I'm testing HMAC authorizations following TPM 2.0 library specification, and I've confirmed all cases works well except the "unbound and unsalted" session case, which uses null buffer as sessionKey with authValue_entity for HMAC calculation.I...
Hi everyone!I’m completely new to microcontrollers and planning to start a simple project, maybe something like a motion sensor for my garage or home. I’ve been looking into ESP32 but I’m not sure. Do you have another option you'd suggest?I’d like so...
