1 Can I use your devices as a SPI or I²C slave? Featured

No you can't. SPI Storm is an advanced SPI, Dual-SPI, Quad-SPI and custom protocol host adapter (Master). SPI Xpress / GP Series devices in SPI mode of operation can be used as SPI Master and/or SPI Analyzer. I2C Xpress / GP Series devices in I2C mode of…

2 Does your devices support the programming of SPI and I2C EEPROM? Featured

As general purpose SPI master and I2C master, the following devices will support corresponding EEPROM programming: - SPI Storm device supports SPI, dual-SPI and quad-SPI protocols and hence, is able to control EEPROM using these procotols. - SPI Xpress and…

3 I need some extra GPIO lines in addition to the SPI Master. Is this possible? Featured

Yes, with SPI Storm, where you have a 8-bit GPO (General-purpose output) port for generating digital patterns, synchronized or not with the serial port. SPI Xpress and GP Series devices in SPI mode of operation do not offer additional GPIO lines.

4 Introducing SPI Xpress Featured

Paper Abstract SPI Xpress is Byte Paradigm’s SPI protocol exerciser and analyzer. It is controlled from a PC through a USB 2.0 high speed interface. It allows debug, analysis, programming and testing of chips and electronic boards that use SPI for chip-to-chip…

5 Can I always reach the maximum SCLK frequency of 50 MHz with SPI Xpress?

No, this depends on whether you are using the SS signal shifting capability. With SPI Xpress (or GP series device in SPI mode of operation), you can position the start edge and the end edge of the SS signals at SCLK edge, 1/2 SCLK period before or after the…

6 How do I proceed if I only wish to read data in SPI-3 mode?

This question arises when the format proposed for the 3-wires SPI protocol (SPI-3) cannot be used for specific slaves. The SPI-3 protocol of the SPI mode of operation is composed of 3 successive phases: Write Phase - Latency - Read Phase. For protocol only…

7 How to de-activate the default addition of clock pulses

On page 6/27 of user guide of spic c library, there is a note saying "default addition of clock pulses can be deactivated". Could you tell me how? You have to use function spi_SetSSClockMasking: parameters = 1 enables the clock masking (hence suppresses the…

8 How to specify 0 bit for read phase using ShiftWrThenRd?

When I called the ShiftWrThenRd for 3-wire spi operation, I found that writing bits followed by reading 0 bit is not successful. The corresponding function return is -401. If the number of reading bits is changed to 1, the operation is successful but the…

9 I would like to define a specific number of clock cycles between my SPI transactions. Is is possible?

Yes, it is. 1) C/C++ interface: please use Idle() or IdleBurst() functions from the SPIIC.dll library - please refer to SPIIC library user's guide. 2) GUI: write/record a script and use the IDLE command in it - please refer to 8PI Control Panel user's guide.

10 I'd like to sniff my serial bus. Will SPI Xpress do the job?

It depends on what is meant by "sniffing" your serial bus. SPI Xpress is a SPI Master and SPI Analyzer. As a SPI Analyzer, it is able to work like a logic analyzer: - from the occurrence of a trigger condition, the device collects data and fills some memory…
