Dev Bugfix: Analog channel 0 overwrites digital channel 0:
The search for the next analog channel was stopped in case the iteration is reset to zero => channel 0 was always sampled, even if no connected sensor was detected. This caused the values of a connected digital sensor to be overwritten. The search loop will now (again) iterate till it finds a new sensor or till the index reachs the active sensor index.

| 13 ##### How to use ##### | |
| 14 ============================================================================== | |
| 15 ADDR_FLASH_SECTOR_0 to/with ADDR_FLASH_SECTOR_5 (256KB) is used for this bootloader | |
| 16 | |
| 17 ADDR_FLASH_SECTOR_23 is blocked and used for Font T48 and image_heinrichs_weikamp | |
| 18 Font T24 for button text is not blocked / protected | |
| 19 other fonts should not be used here | |

| 24 STM32F10xxx In-Application programming CD00161640.pdf 2010 | |
| 25 ============================================================================== | |
| 26 User program conditions | |
| 27 The user application to be loaded into the Flash memory using IAP should be built with | |
| 28 these configuration settings: | |
| 29 1. Set the program load address at 0x08003000, using your toolchain linker file | |
| 30 2. Relocate the vector table at address 0x08003000, using the | |
| 31 "NVIC_SetVectorTable"function or the VECT_TAB_OFFSET definition inside the | |
| 32 "system_stm32f10x.c" | |
| 33 | |
| 34 can be found here system_stm32f4xx.c | |
