From 8a450d5b7bab738fe882f8675ec8a7f8fba7b306 Mon Sep 17 00:00:00 2001 From: Romain Forlot Date: Sat, 23 Nov 2019 13:39:52 +0100 Subject: bitfield-c: use unsigned int instead of uint8_t Use unsigned int instead of uint8_t upon destination and source array length. This is needed to handle gathered multi-frames message data which could be greater than 1 simple messages.
