Hi All, I have a circuit that works very well and uses the BTA24-800CWRG device housed in a TO-220 through-hole part. I currently have it bolted to a large enough heatsink and a fan above it just for safety and to keep it cool. I am now updating the...

Hi All, I am using the STM32H723 device and have used the HAL functions and they work but I find the SysTick or any timebase interrupts my code. Timing is critical; if the data from the serial port is interrupted by the SysTick interrupt, I lose data...

Hi All, I managed to be able to bootload the STM32H723 device using the STM32 Flash Loader (STBootLib) but do not like how I have to pull BOOT0 high and also reset the device right before I program the device and then when the boatloading is done res...

Hi All, I am looking to use the STM32H745 dual-core chip in my next design. I currently use a CH9121 device that handles the transparent ethernet to UART bridge for me and looking to incorporate this functionality into the STM32H745 on the M4 process...

Hi All, I am using the STM32H723 device and have 8 GP outputs going out to a GreenPAK device to set the exact bit delay and muxing the outputs per the customer configuration. Due to the nature of the application, I cannot afford to integrate the logi...

Okay, thanks for this I appreciate it!

Hi TDK, Okay, how do I jump to the bootloader from my application? In my design, there will be an "application" UART and a "programming/bootload" UART. Do you know of working code examples for the STM32H723 device that you can share that jumps to th...

I'm mainly concerned with data throughput. I want the one processor handling the ethernet stuff while the other is handling the data and motion control stuff. For slow speeds, I'd consider just using one processor but since I want high-speed operatio...

Yes, I am aware of writing the pins this way. Thank you for this though.

Hi Bob, Ahh ok, I will configure the outputs as open-drain and may need to use external pullups because I may need to tune the resistors due to the speed.Funny you should mention GPIOA as I am using bits 0-7 for the first group and 8-15 for the sec...
