dsPIC30F4011 ile glcd skop ve spectrum analizör

Devre dsPIC30F4011 mikrodenetleyicisi ile gerçekleştirilmiş ACD bölümünde MCP6S21 kullanılmış bilgileri 128X64 grefik lcd (Lumex LCM-S12864GSF) üzerinde görüntülüyor. Projeye ait tüm kaynak kodlar, şemalar verilmiş ayrıca detay açıklamalar (ingilizce) var

Facing the demise of my Tektronix 2213 in an unfortunate shipping journey, I
faced the decision of either purchasing an expensive CRT to get it running again, or
spending my nights surfing ebay for another scope.

The oscilloscope consists of an input stage consisting of a resistive attenuator with
1Mohm impedance, a switch to remove or insert a capacitor for AC or DC coupling,
followed by several amplifiers. The first amplifier is a unity gain inverting buffer,
followed by a level shifting circuit to center the signal around .5Vcc (2.5V) for the PGA
and ADC. The stage immediately preceding the ADC pin on the dsPIC is a Microchip
MCP6S21 PGA
