Setup: picaxe development board, 40X2 chip, very simple circuit/code that just reads data from a ROM chip and writes it out with sertxd one byte at a time. Problem: at 8mhz / 9600 baud, it's "kind of" stable, it's very easy to interrupt the data flow and lose a few bytes. At 16mhz it loses...

Are there any newer drivers available or planned? On Windows 11 with Core Isolation enabled, the drivers will just throw an error 39 and fail to load. This is the default setting now for many machines including all supplied by Lenovo for example, and an important security feature.

I needed this for a project I'm building but couldn't find one - so I designed this by measuring the part and a test PCB that just arrived shows it was correct. You'll want to be mindful of the barrel position marked as it sets the edge of your PCB (or add a cut). Hardest thing was getting...

I have a program that uses over half of the available 1024 bytes of scratchpad space on the 40X2 chip. I have the chip type selected correctly in my basic program and if I load the problem onto the PICAXE itself it runs fine. If I try to run simulataton while another basic program is loaded in...

I have some code controlling the STROBE line on a switch matrix chip - switches in the matrix are controlled by setting the address inputs correctly, setting the data to high (on) or low (off), then strobe should go high then low for it to set the selected switch. Pin A.6 is the strobe pin and...
