TheGhastModding, Do you feel up to the challenge of porting that to the Uzebox?  I can send you some hardware if you think you can give it a shot :)

SAM4S - USART SPI Master with PDC DMA - delay between Tx bytes
Sadly my requirement is not quite as simple as making the pulse train.   It is described in an unanswered/unloved thread here

SAM4S - USART SPI Master with PDC DMA - delay between Tx bytes
Glad to hear it works.   I've never actually tried it on an ARM, but it is an old trick I've used many times on old 8 bit CPUs.   I'm still trying to figure out a way to...

Prototype PCB Manufacturer - Recommendations Wanted
I use to use Elecrow for cheap boards.  I switched to JLC now.   With JLC I have never felt the need to pay extra for faster service as they normally get completed in 2...

need to program 100+ attiny13A: which programmer board?
OP.  Is the circuit incompatible with ISP programming (you HAVE to do the programming while not connected)   If not then get yourself an 8 pin IC clip and use it with...

SAM4S - USART SPI Master with PDC DMA - delay between Tx bytes
Have you tried using the USART in SPI slave mode and feedining the slave clock via an external pin that is looped back from a free running PWM/TimerCompare output at the correct...

How do I avoid a bus collision? A question for true experts.
Totally looks like the TX Enable of the master is staying active too long.   Is the master using a crappy USB to RS485 adapter that simply uses  an RC-Diode time...

is this bread boarded.  Is there enough inductance in your leads to have ringing or oscillations  that exceeds the diodes rating?   I assume you have checked you CC...

Advice on touchscreen LCD?
At scale - a generic 16x2 LCD is not cheaper than a TFT unless you have to include the cost of a larger battery to run the colour one.   A modern chip on glass led backlit...
