The i2c lines were also 'pulled up to 5 Vdc via 10 kΩ resistors to ensure correct operation. I am having the same I2C issue as you, and cannot resolve it. For slow I/O like I2C we often do not write timing constraints. 1, January 2000, except for the following areas: • High-speed mode (Hs-mode) is not currently supported by the AXI IIC core. To start test we have to send start command to USB EP1 which will cause I2C write to FPGA register and start test. In a 'MIO Configuration' expand 'I/O Peripherals' tree and enable 'UART0', both I2C and both SPI. If it matters I'm using xilinx tools and plan to synthesize this to an xc3s50 or similar. Because the zc706 has a DDR memory connected to the hps and another to the programmable logic, we use the second one as a high-speed buffer ( adc_fifo ). 6 vvcc操作。 p> sn74alvch16820的触发器是边沿触发的d型触发器。在时钟(clk)输入的正跳变时,器件在q输出端提供真实数据。 基于DE2的开源片上系统Freedom E310移植 - 全文-Freedom E310是第一款基于RISC-V指令集架构的开源商业片上系统,可以依据具体应用场景对其进行深度定制,在简单介绍Freedom E310的基础上,给出了将其移植到Altera的DE2开发平台的详细步骤。 C iobuf C iserdes_mem C jp_channel C latch_g_ce C lens_flat393 C lens_flat393_line C level_cross_clocks C level_cross_clocks_ff_bit C level_cross_clocks_single_bit C level_cross_clocks_sync_bit C link C logger_arbiter393 C masked_max_reg C mcntrl393 C mcntrl393_test01 C mcntrl_1kx32r C mcntrl_1kx32w C mcntrl_buf_rd C mcntrl_buf_wr Revision: 776 http://armadeus.
