1.2.BF.5.8 Xmas Edition - new FFT windows - added 2048 and 4096 points FFT - improved FFT algorithm - moved FFT tables from RAM to flash memory planned issues: - menu scrolling for window menu, mode menu and length menu - frequency scrolling for 2048 and 4096 points FFT Attention!!! Attention!!! Attention!!! Attention!!! Attention!!! At the first start of the new firmware there will appear a popup with progress indicator that informs You about writing the new FFT tables into flash. This may take 10 minutes. Don't switch off Your DSO, take a coffee and wait until it is done. If You interrupt this process it will appear again at the next startup until it is completely finshed. After that it won't appear again. 1.2.BF.5.9 - FFT menu scrolling - some bugfixes 1.2.BF.5.10 - new scaling factors for preamp resistances 24.9 Ohm / 180 Ohm in the hardware menu Combination of 2 x 24.9 Ohm and 1 x 180 Ohm (174 Ohm) is recommended! If there are any questions please ask in the hardware thread. English comments are welcome - although this is a german forum. https://www.mikrocontroller.net/topic/255209#2631781 For further details please read the changelog and the file Special Functions.txt Please don't forget to make a default setup and check your calibration after flashing!
