Re: User Break Controller for SH7305

The UBC of the SH7305 exists and works as expected. But the process to get it working is a bit complicated. First you need some assembler run time library, which must be placed in an unused RAM-area. I append the source of the assembler run time library only for a first reference. There are some inc...

Re: Connect to FX-9750gii through 3pin using audio

The [Calc Receive Data] and [Calc Transmit Data] ports strictly require TTL-level. This is the baseline, if you don't want to use additional active hardware. If it is possible to operate the computer audio ports as digital ports at TTL-level, at least the electrical characteristics would match. The ...

Re: Unraveling the secrets of the KEYSC

Now that's what I was looking for when I created this topic. Erm... why didn't you post this earlier? :think: Do you know the bit pattern of these registers and their meaning? There seems to be nothing about them in your chm documentation. I posted this about two years ago: SH7305 registers (comple...

Re: No FPU in fx-9860G II?

By the way, this is one question. About SSCGCR (Spread spectrum control), This seems not to be in SH7724, but does any other CPU have SSCGCR? There is a register OSCWTCR with the same address on the SH7730, but I do not know, if it is related to SH7305 SSCGCR. Above that I could not find any clues ...

Re: No FPU in fx-9860G II?

Perhaps the following list comes in handy in some situations: PTA0 (1) : Port A0 / FSI_LRCK / MSIOF0_TSYNC in PTA0 (2) : Port A0 / FSI_LRCK / CLK1 / MSIOF0_TSYNC out PTA1 (1) : Port A1 / FSI_BCK / MSIOF0_TSCK in PTA1 (2) : Port A1 / FSI_BCK / CLK2 / MSIOF0_TSCK out PT...

Re: fx-9860GII OS footer question

In some cases the functions, which access the storage memory, use sector arrays like .data.l h'270000, h'280000, h'290000, h'2A0000, h'2B0000 .data.l h'2C0000, h'2D0000, h'2E0000, h'2F0000, h'300000 .data.l h'310000, h'320000, h'330000, h'340000, h'350000 .data.l h'360000, h'370000, h'380000, h'3900...

Re: fx-9860GII OS footer question

A few examples: On fx9750 OS 2.02 with 8024FFE0:"2011.0801.1251" and 8024FFF8:h'10440FE6 there exists the TestChecksums-procedure at 800396C4. On fx9860 OS 2.02 with 8024FFE0:"2011.0801.1921" and 8024FFF8:h'0F746332 there exists the TestChecksums-procedure at 8003E01C. On fx9860 ...

Also for all Files after the first File im getting send 0x15 04 0 6C the overwrite impossible error packet back to me. How should i react to that and do i need to send some command after the data packages for one file to signalize that this file is done and a new one begins? At the moment im just s...

Re: Transfer Files from Arduino to Casio-FX-CG20

The problem was my casio. I bought a new one and now it's working like it should. The only kinda weird problem im still getting is: When transfering large Images, im getting an error package after around 120 data packages(i think its the last Data package). 0x15 01 0 6F//i've read in your pdf that ...
