UART instability fix with high interrupt load (#283) * Fixed UART overrun error * Added stability test scripts * Refactored UART code. ESP/GPS now uses DMA in circular mode to directly write into the ring buffer, saving a bunch of interrupts and potential race conditions. * Changed stability test to use amount of bytes instead of amount of non-zero messages, since the ring buffer pointer is only updated on half or full DMA transfer or on line idle (e.g. no more 1 char messages from the gps) * Increase data limit. It's too low sometimes in normal operation * Forgot to set write pointer in ring buffer * Increased test limit even more
