I'm having a hard time deciding if I should try your firmware, and can't find information on how it compares to the original.

I'm annoyed at the fact that the trigger and measurements disappear at slow sample rates, and that the time scale can't be changed on a stopped screen.

Great feat reverse engineering the device, regardless of any changes (or lack thereof) you may have made to it.

Thanks!

Today I have tried the base calibration and it was stuck on Calibrating... Need to power cycle the scope.

As I thought, the SW may have an issue or the scope is broken, I have updated to latest version. Was worth it, because now I can see the measurements. But calibration still freezes the scope.

Just now I have found out, that the trigger was set to Normal. So I have set it to Auto and now calibration has passed successfully.

BTW: AutoSetup was stuck, too. And with trigger set to Auto, it works as expected.

can you make this support with a mouse usb ?

i need help. can anyone explain line by line this code :

//Initialize the control lines for communication with the FPGA (PE8:10 output)
#define FPGA_CTRL_INIT() *FPGA_CTRL_CFG_REG = (*FPGA_CTRL_CFG_REG & 0xFFFFF000) | 0x00000111

//Initialize the clock line to high
#define FPGA_CLK_INIT() (*FPGA_DATA_REG |= 0x00000100)

//Set the different target options for communication with the FPGA
#define FPGA_CMD_WRITE() (*FPGA_DATA_REG = (*FPGA_DATA_REG & 0xFFFFF9FF) | 0x00000600)
#define FPGA_CMD_READ() (*FPGA_DATA_REG = (*FPGA_DATA_REG & 0xFFFFF9FF) | 0x00000400)
#define FPGA_DATA_WRITE() (*FPGA_DATA_REG = (*FPGA_DATA_REG & 0xFFFFF9FF) | 0x00000200)
#define FPGA_DATA_READ() (*FPGA_DATA_REG = (*FPGA_DATA_REG & 0xFFFFF9FF) | 0x00000000)

//Clock control
#define FPGA_PULSE_CLK() (*FPGA_DATA_REG &= 0xFFFFFEFF);(*FPGA_DATA_REG |= 0x00000100)

//Put data on or get data from the FPGA databus
#define FPGA_SET_DATA(x) (*FPGA_DATA_REG = (*FPGA_DATA_REG & 0xFFFFFF00) | (x & 0x000000FF))
#define FPGA_GET_DATA() (*FPGA_DATA_REG & 0x000000FF)

There is a problem with calibration in my scope. Generally CH1 overestimates the measurement by 5% and CH2 has 200 mV offset sometimes, but this vary from calibration to calibration.

I want to debug this problem and have started analyzing the scope_do_channel_calibration function. But the overall FPGA concept in this scope is unclear to me, especially in context of calibration commands. Could you shed some light on this topic and/or or point me the right place in the FNIRSI-1013D-1014D-Hack repository.

Does this firmware support the newer model ad1013d ii?

Please help me. I did it according to the instructions, but something went wrong. When rebooting 1013d Pecos SCOPE and then the error is SD ERROR.

I am 100% sure I've posted this earlier today but it is not here.

I followed all the steps to use your custom firmware on Daniu ADS1013 version but all I can see on boot is ~200ms of the splash screen and then the entire screen is magenta filled, nothing else.

Does that mean that the custom firmware is not compatible with the "Daniu" branded scope?

It comes with a 1GB SD card, so I tried an 8GB one but got the same result, so I guess it is not about the card size.

I tried to read the flash from the 1013D to make backups, but after that the oscilloscope won't turn on anymore. Does anyone have a memory backup?
