Create symbol for other two modules(non top-level)
Import and wire these symbols in top-level module.
But observe the correct data directions between symbols.
I tried to find these smd part codes
D3L 48(?FET) and RJ471A (Switching supply)

Sorry for my mistake! I pressed the big IC on top right and the calculator works again. Then I resoldered it and working.
But here a picture:
Thank You!
When I insert batteries then happens nothing until "ON" key pressed. If powered on all functions OK. But when I press "2nd""Off" then screen is erased and remain light grey. If press "ON" again then all Ok again.
The calculator went trough on customs x-ray gate when arrived.
I searching for TI-83 calculator schematics, but nothing found.
The issue: When I insert batteries into calculator and power it on....OK! But when auto power off or 2nd/off pressed the screen contents disappear and the screen remain light grey. Current consumption is 20mA when power is off and...
Hi! I think 10KW is reflected as any radiation or converted to heat on collector element. The collector elements not convert this power to electic, because the output is limited at 20KW. The energy must not lost.
But I don't know the right answer...
To eeefreakians: Try to measure temperature...
I get same problem at first on mc68000+adc0808. When I tied all input together I get the good result of input signal because my addressing rutine was bad.
If tied together the inputs, one of randomly addressed adc get good result. If read it without addressing, get good result. But it is...
I used an adc0808 on mc68000 and I first get random numbers when clocked and addressed it with mc68000 out port.
First try all inputs tied together and check the result. If you read good value then address latching not work. If the result garbled then check the clocking.
I get best result with...
Fastrax3216 GPS module (IT0302 series) pinout and datasheet
Hi! I need some help please!
I searching for datasheets,pinout and command sets of Fastrax 3216 GPS modules(IT0302 series). But I can't find anything on google.
Hi! The IRF need more higher gate voltage in this scheme than +24v. Or need rearrange the loads and the FET in the circuit. I think this circuit will work if the FET source will be on the gnd and the load between the drain and +24v. And need adjust the voltage of pulse on the gate.
I think max232 rx/tx and pic rx/tx tied together with jumpers on the given link. RS232 standard is point to point(beetwen two units). Two tx signal on one wire. This possible caused garbled or missing bytes. For the max232 you can use a second(soft)UART on not connected IO pins.
(sorry for my...
