WebMar 31, 2024 · Memory Issues What is a MemoryError? Memory allocation errors happen when you're trying to store too much on the board. The CircuitPython microcontroller boards have a limited amount of memory available. You can have about 250 lines of code on the M0 Express boards. WebOk, I'm new to all things programming and microcontrollers, but after beating my head trying to get multiple spi displays to work with a pico on circuitpython I want to make sure I understand this correctly. There is an artificial limit in circuitpython, that isn't mentioned anywhere, that limits the number of displays you can use to 1.
