| 10.01.2009 | keyboard.html | Error in source code for keypad | corrected | Carl Rheinlaender |
| 26.08.2007 | switch_schem.gif | Akkuload-Analog schematic: Error in wiring of channel 3 | corrected | Jonny Bijlsma |
| 02.05.2005 | akkucalc.asm | Akkuload: Caused by a serious bug in the calculation routine, the currents are by a factor of roughly two too small, and are displayed false. | Corrected. | Sebastian Mazur |
| 06.01.2005 | gavrasm and Pony-Prog | If you use gavrasm for assembling, and if you add more than one ORG directive within the code, and if you use Pony-Prog for burning the Hex- and Eep-files to the AVR, the shift in adress, caused by the ORG directive, is implemented in INTEL-Hex-format, but ignored by Pony-Prog. Be cautious when using more than one directive. | Pending | (Self) |
| 01.10.2004 | CALC.html | False description of the BLD and BST instruction | Corrected | Mark |
| 05.12.2003 | Lcd4IncE Lcd4IncCE | Bug in the LCD-Clock asm file prevented compilation | Corrected | Dan Carroll |
| 05.07.2003 | FP_CONV10, HTML .ASM | A missing code line caused calculation errors | Corrected | Thilo Mölls |
| 24.12.2002 | exp2313.gif | Corrected the pullup resistor in the experimental circuit, due to occasional reset problems reported, to a lower value | Corrected | Andreas Wander |
| 24.12.2002 | (several) | Corrected an error in the source code for the 4-Bit-LCD software | Corrected | Jan de Jong |

The interrupt routine has a serious bug. The result is an unhandled interrupt, delaying execution of the program by approx. a factor of 30. As this routine requires external SRAM and so doesn't work with STK500, I removed these codes and will not provide a debugged routine instead. | Removed | (myself) |
| 23.12.2001 | clock.gif clock.pdf | RTS and CTS between the plug and the line driver were exchanged. The plug is to be connected to the PC using a crossed link for RD/TD and RTS/CTS. PB4 must be set to 0 to activate the CTS line. | Corrected | Wim Korevaar |
| 25.11.2001 | bcdmath.inc sioint.inc testsint.asm | Download of the inc-files results in an error message from the server. These files were renamed to .asm and the calling asm file corrected. | Corrected | Axel Rühl |
| 24.09.2001 | (Several) | Errors using .DEF and .EQU | Corrected | Stefan Beyer |
| 03.06.2001 | CLOCK.html CLOCK.asm | When working with a DCF77 signal the seconds are incorrect (59.th second is already 0). | Open! | - |
| Error in the calculation of tens of monthes from the DCF77 signals | Corrected | Thomas Baumann | ||
| (Several) | Some minor additions and changes in the text | corrected | Frank Dalchow | |
| TEST1.html TEST1.asm | Some translation errors in the text | corrected | Brian Tangney | |
| 02.12.2000 | TEST1.html TEST1.asm | It was stated that the frequency of the LEDs is 800 kHz. In fact it is only 667 kHz! | corrected | Timo Engelmann |
